Objective Improve the economic benefits of raffinate oil application by using raffinate oil upgrading technology.

Methods By comparative analysis of raffinate oil upgrading technology and C₅/C₆ isomerization technology, combined with actual production and operation data, the industrial application of raffinate oil upgrading technology was discussed.

Results The RON of produced modified gasoline is 9 to 10 units higher than that of the raffinate oil, which created considerable economic benefits. At the same time, after the modification reaction, the olefins content in the raffinate oil reduced, which effectively reduced the olefin content in the gasoline blending pool and created favorable conditions to produce high-grade gasoline for the entire plant.

Conclusions The flow of raffinate oil modification technology is simple, the investment is small, and the safety is high. Therefore, it has good economic benefits and broad application prospects.
